For this study, 123 adult alcohol dependent subjects were recruited from collaborating treatment centers, randomly assigned to one of two equal study arms, and followed for 26-weeks (Period 1, Randomized Controlled Trial, RCT). The RCT evaluated the efficacy of the meditation intervention using self-reported alcohol consumption as primary, and drinking-related harms and subject treatment satisfaction and adherence as secondary outcomes. It also gathered preliminary data on potential mechanisms of meditation action. After the completion of their 26-week RCT (Period 1), controls were eligible to receive the meditation intervention ("cross-over"), and all participants were followed-up for additional 26 weeks (non-randomized Period 2).
